Obvious gouging is obvious
As in any global, or even national, scare, gouging was inevitable and obvious. What else are all the twats with garages full of bog roll going to do with it?
Prices on everything should have been frozen as soon as global spread was noticed, was harsh penalties for anyone profiteering. But no, that's not democratic.
Supermarkets should have imposed strict item limits (say 2 of anything max) as soon as it was clear people were emptying the shelves. But no, that would get in the way of their profits.
Expecting people to behave in troubled times is never going to work. Always profits to be made, and arseholes to make them off the desperation of others.
